Installing SLX crank on Pitch, having problems.

Did you even adjust the front derailluer

So I took the Deore crank off my wife's Pitch and installed a new SLX crank, but now I'm having trouble getting it to shift properly. The old Deore crank had one spacer installed on the drive side, so that's what I did this time, and that's no bueno. I can't get the derailleur to throw the chain far enough to ramp up on to the middle chain ring. Anyone else have this set up? Am I missing something?

I have not use this same set up, but I have replaced many crank sets and had little troubble getting the chainline set back up to shift, generally I am upgrading to XT and I will say the better chain rings sure do shift really well .

Stupid question , ---did you make sure the chain rings were on and alighned correctly on the new crank's-?

Also you can generally tell if the chainline is to far away from the derailer because it looks funny .

Can you over throw the derailer and get it to grab the pins ?

Yes.

Chain rings are aligned correctly, and the derailluer looks like it's aligned correctly.

I can get the der to throw the chain almost close enough, but you have to click up to 3 to finally get it to catch the pins. I can adjust the der waaaay out and get them to catch, but then it won't drop back down into the granny ring.

Shouldn't make much difference, but you can go to the Park tools website to see a breakdown of spacer placement. All external BB cranksets I've used have taken one spacer on the drive side, barring e-type der., etc.

It sounds like it is out alittle to far , I have had to pop in the old right side crank half and measure the old chainrings distance from the derailer , ---then pop back the new set up and compair .
some of these can be off more than they should be and will require different spacing .

I have had some Hammerschmidts that were a pain to get the tabs repaired and get the crank set in nice and centered, I had to make several spacers untill I got one perfect, ------ :madman:

I did gloss over the simple stuff. I assume you torqued each external bearing cap down all the way. I have several sets of SLX cranks. Each time I remove and remount (just did it this weekend), I fully seat the drive-side crankarm with a rubber mallet.

Of course, if it weren't fully seated, you likely wouldn't have gotten the left arm properly mounted, but it's an idea.
